Calibrachoa plant named ‘Balcabpiken’

ABSTRACT

A new and distinct cultivar of  Calibrachoa  plant named ‘Balcabpiken’, characterized by its light pink and rose bicolored flowers having dark venation, medium green-colored foliage, and moderately vigorous, compact, mounded-trailing growth habit, is disclosed.

Latin name of genus and species of plant claimed: Calibrachoa×hybrida.

Variety denomination: ‘Balcabpiken’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Calibrachoa plant botanically known as Calibrachoa×hybrida and hereinafter referred to by the cultivar name ‘Balcabpiken’.

The new cultivar originated in a controlled breeding program in Elburn, Ill. during November 2005. The objective of the breeding program was the development of Calibrachoa cultivars with attractive flower coloration, medium green-colored foliage, and a moderately vigorous, mounded-trailing growth habit.

The new Calibrachoa cultivar is the result of cross-pollination. The female (seed) parent of the new cultivar is the proprietary Calibrachoa×hybrida breeding selection designated 2210-1B, not patented, characterized by its white-colored flowers having slight purple venation and a purple-colored throat opening, medium green-colored foliage, and moderately vigorous, mounded-trailing growth habit. The male (pollen) parent of the new cultivar is the proprietary Calibrachoa×hybrida breeding selection designated 2198B-1, not patented, characterized by its salmon-colored flowers having red venation, medium green-colored foliage, and moderately vigorous, compact growth habit. The new cultivar was discovered and selected as a single flowering plant within the progeny of the above stated cross-pollination during May 2008 in a controlled environment in Elburn, Ill.

Asexual reproduction of the new cultivar by terminal stem cuttings since May 2008 at Elburn, Ill. and West Chicago, Ill. has demonstrated that the new cultivar reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

The following characteristics of the new cultivar have been repeatedly observed and can be used to distinguish ‘Balcabpiken’ as a new and distinct cultivar of Calibrachoa plant:

-   -   1. Light pink and rose bicolored flowers having dark venation;     -   2. Medium green-colored foliage; and     -   3. Moderately vigorous, compact, mounded-trailing growth habit.

Plants of the new cultivar differ from plants of the female and male parents primarily in flower color.

Of the many commercially available Calibrachoa cultivars, the most similar in comparison to the new cultivar is CAN-CAN Strawberry ‘Balcanerry’, U.S. Plant Pat. No. 21,193. However, in side by side comparisons, plants of the new cultivar differ from plants of ‘Balcanerry’ in at least the following characteristics:

-   -   1. Plants of the new cultivar are less spreading, as measured by         plant width, than plants of ‘Balcanerry’; and     -   2. Plants of the new cultivar have a flower color different from         plants of ‘Balcanerry’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show, as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. Colors in the photographs differ slightly from the color values cited in the detailed description, which accurately describes the colors of ‘Balcabpiken’. The plants were grown in 4-inch pots for 8 weeks in a greenhouse at West Chicago, Ill. Plants were given one pinch at transplant.

FIG. 2 illustrates a close-up view of an individual flower of ‘Balcabpiken’.

DETAILED BOTANICAL DESCRIPTION

The new cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length, without, however, any variance in genotype.

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England, 2007 edition, except where general color terms of ordinary significance are used. The color values were determined in April 2011 under natural light conditions in West Chicago, Ill.

The following descriptions and measurements describe plants produced from cuttings from stock plants and grown in a glass-covered greenhouse under conditions comparable to those used in commercial practice. The plants were grown in West Chicago, Ill. in 4-inch pots for 8 weeks utilizing a soilless growth medium. Plants were given one pinch at transplant. Greenhouse temperatures were maintained at approximately 70° F. to 77° F. (21° C. to 25° C.) during the day and approximately 65° F. to 68° F. (18° C. to 20° C.) during the night. Greenhouse light levels of 2,500 footcandles to 6,000 footcandles were maintained during the day. Measurements and numerical values represent averages of typical plants.
